GRAIN-SHOCKER FOR HARVESTERS.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed'Fehruary 18,1907. Serial No. 357,982,

To all whom it may concern:

Be it known that I, HERBiER'r HUGH WATT, a citizen of the United States,residing at St. Thomas, in the county .of Pembina and State of NorthDakota, have invented a new and useful Grain-Shocker for Harvesters, ofwhich the following is a specification.

This invention has relation to grain shockers for harvesters and itconsists in the novel construction and arrangementlfof its parts ashereinafter shown and described.

The object of the invention is to provide a means for assembling andcollecting bundles of grain as they are tied by the mechanism of theharvester and confine the said bundles until a suflicient number hasbeen collected when the said bundles are lowered into position upon theground in the form of a shock.

The device consists primarily of a series of sprocket chains havingspring fingers which are adapted to engage the bundles and convey themto a receptacle.

Means is provided for varying the altitude at which the said chainsshall travel, thereby, rendering the device applicable to tall or shortgrain. The said receptacle is provided with a removable bottom which isswung out of the way when the shock is about to be deposited I upon theground. The said receptacle is also provided with a hinged side orsection having means for swinging the same open for dropping the shock.Said means will also hold the sectional side of the receptacle in'closed position sufficiently tight to bind bundles therein even thoughthe bottom of the receptacle is swung out of the way. Consequently thesaid bottom may first be moved and the side section subsequently openedfor dropping the shock.

In the accompanying drawingz-Figure 1 is a top plan view of the shocker.Fig. 2 is a side elevation of the same with parts broken away, and Fig.3 is a side elevation of one of the disks provided with an eccentricgroove.

The shocker comprises the arm 1 which is attached at its inner end tothe frame of the harvester. Said arm is provided with an outer hingedportion 2 which is arranged to swing vertically. The said hinged portion2 is provided with an upstanding lug 3 to the end of which is attached adraw rod 4. The free end of said rod 4 lies in the vicinity of theoperators seat, not shown, and the said rod is adapted to be moved manu'ally. The sprocket wheels 5 are fixed to the shaft 6 which is journaledfor rotation in the frame of the harvester. The sprocket wheel 7 is alsofixed to the shaft 6, and the sprocket wheel 8 is fixed to the sicklebar shaft 9 and the sprocket chain 10, passes around the wheels 7 and 8.The sprocket wheels 1.1 are journaled upon spindles 12 which are hingedto the portion 2 of the arm 1. Thus the said sprocket wheels may swingin arcs in lateral directions with relation to the said portion 2. Thesprocket wheels 13 are similarly mounted at the end of the portion 2 ofthe arm 1. The sprocket chains 1.4 pass around the sprocket wheels 5,and 13 and over the sprocket wheels 11. There is sufficient play betweenthe links of the said chains 14 as to permit the same to twist laterallyin passing from one of the wheels 5 to the opposite upper wheel 11 andfrom one of the lower wheels 11 to the opposite wheel 7. The said chains14 are provided at intervals with the prongs or fingers 15. The baseportions of said prongs are convolute as at 16 and consequently lendresiliency to the said prongs, which may bend back when delivering thebundles.

The skids 17 are attached to the deck of the harvester and are locatedabove the wheels 5. The arm 18 is pivotally supported at its inner endupon the frame of the harvester and is provided at its outer end with acircular platform 19. Said arm is provided with a laterally extendinglug 20 to the end of which is pivoted a link 21. The inner end of thelink 21 is provided with a pin 22 which enters the eccentric groove 23provided in the cam 24. Said cam is fixed upon a shaft 25 which isjournaled for rotation. The said platform 19 constitutes the bottom ofthe bundle receptacle. The arm 26, is attached at its inner end to theframe of the harvester. The receptacle 27 is fixed to the outer end ofthe arm 26 by means of the bolt 26 and may be tilted laterally at anydesired angle and the receptacle side-section 28 is hinged to the edgeof the receptacle 27. The inner edges of the receptacle 27 and thesection 28 are provided with the recessed portions 29 and 30respectively and it is through said recesses that the outer portion ofthe portion 2 of the arm 1 passes into the space between the receptacle.The outer end of the rod 31 is pivotally attached to the outer side ofthe section 28. The inner end of the said rod 31 is pivoted to theworking end of the lever 32 which in turn is fulcrumed to the frame ofthe harvester. The link 33 is pivotally attached at one end to the powerend of the lever 32 and at its opposite end is provided with a pin 34which enters a groove 35 provided in the disk 36. Said disk is fixed tothe shaft 25 and rotates with the same.

The operation of the device is as follows:The sprocket wheel 7 .rotatescontinuously, consequently the sprocket chains 14 are in continuousmotion. The bundles of grain pass from the deck of the harvester overthe" skids 17 and fall upon the chains 14. Each bundle is engaged by theprongs 15 which enter the bundle in the vicinity of the binding twinethereof. As the chains 14 move at their upper portions toward the Wheels13 the bundle is turned from a horizontal position into a verticalposition and is carried with its butt end upon the platform 19 andbetween the side of the receptacle 27 and the section 28. When thebundle is carried around upon its end within the receptacle 27 until itcomes in contact with the edge of the section 28 having the recess 30,the prongs 15 will be pressed back by the resistance of the bundle andwill escape the same, leaving it in the said receptacle. The next bundlewill come in contact with the preceding bundle and the operation abovedescribed is repeated until the receptacle is filled with bundles. Whenthis occurs the link 33 is moved longitudinally by means of itsengagement with the eccentric groove of the cam 24. The lever 32 isswung upon its fulcrum and the rod 31 is moved toward the harvesterwhich draws in the hinged section 28 of the bundle receptacle and thesaid bundles are pinched together at their upper ends and confined. Whenthis occurs the link 21 is moved longitudinally by reason of itsengagement with the eccentric groove 23 provided in the cam 24,consequently, through the lug 20 the arm 18 is swung laterally and theplatform 19 is carried from under the bundle receptacle. The section 28is then swung open by a reversal of the movement of the parts 31, 32 and33 and thus the bundles are liberated and fall to the ground in the formof a shock. After the shock is deposited the platform 19 moves backunder the bundle receptacle by a reversal of the movement of the parts18, 20, and 21 as above described.

The hopper 27 may be of any desired shape and if necessary may beprovided with a supporting wheel.

Flexible belts of rubber or leather may be substituted for the chains 14if desired.

Having described my invention What I claim as new and desire to secureby Letters-Patent 1.-A shocker comprising a bundle receptacle havingmeans for confining the bundles, a bottom for the receptacle mounted foredgewise movement in the are of a circle and means for deliveringbundles to the receptacle.

2. A shocker comprising a receptacle having means for confining bundles,a bottom for the receptacle, a pivoted arm supporting said bottom andadapted to move the bottom edgewise, a means for swinging said arm andmeans for delivering bundles to the receptacle.

3. A shocker comprising a bundle receptacle having means for confiningand liberating bundles, a sprocket chain moving in a twisted orbit,sprocket wheels supporting said chain and bundle-engaging prongs carriedby the chain, said chain entering and emerging from the bundlereceptacle. 1

=1. A shocker comprising a bundle receptacle having means for confiningand releasing the bundles, a bundle conveyer comprising an arm having ahinged outer portion, sprocket wheels located at the inner and outerportions of said arm and lying in different planes, a sprocket chainpassing around said wheels and having bundle engaging prongs. 7

5. A shocker comprising a bundle receptacle having means for confiningand liberating bundles, a bundle conveyor comprising an arm, sprocketwheels journaled upon the arm and lying in different planes, a sprocketchain passing around the wheels and having bundle engaging prongs withcoils at the bases of the prongs.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.

HERBERT HUGH WATT.
